  • Patent number: 11810278
    Abstract: Techniques for generating a fused enhanced image. A first image is generated using a first camera of a first modality, and a second image is generated using a second camera of a second modality. Pixels that are common between the two images are identified. Textures for the common pixels are determined. A camera characteristic, which is linked to noise, is identified. A scaling factor is applied to the textures in the first image. A first saliency is determined using the scaled textures. A second saliency is determined using the textures from the second image. An alpha map is generated and reflects edge detection weights that have been computed for each one of the common pixels based on the two saliencies. Based on the alpha map, textures are merged from the common pixels to generate the fused enhanced image.

The sideview mirror assembly can include a camera located in the body about the sideview mirror housing. The camera can have a field-of-view including an above-horizontal region directed rearward toward an overhead target position past the sideview mirror housing. The camera can be mounted for movement relative to the body between a normal position, in which the sideview mirror housing intersects the camera and the overhead target position in the above-horizontal region, and an extended position, in which the sideview mirror housing does not intersect the camera and the overhead target position in the above-horizontal region. Movement of the camera from the normal position to the extended position can unblock camera visibility of the overhead target position by the sideview mirror housing.
